May it be physical of the virtual classroom, form a habit to write down key points, solved problems in your notebook. Typically, online sessions are recorded for future reference. However, it is advisable to form effective note taking habits. When your tutor shows how to calculate complex volume integral, ensure that you immediately note down in your notebook.

While online tutoring, form a habit where you talk and tutor writes. The online tutor could not see you writing in your notebook. So you explain the steps louder while he writes on the whiteboard. This will help you clarify your own understanding and your tutor will get insight on your understandings and confusions. This will boost up learning Math Calculus.

Form a practice to solve problems of the lessons learnt with the tutors. The amount you learn Calculus purely depends on how much effort you put into solving problems. Share your work with your tutor. The tutor will give effective feedback/suggestion if required.

If you have tried solving complex Calculus problems but failed to arrive at the result then take a snap of your work and mail it to the tutor before you start a session. The online tutor will work out in prior, find out difficult areas and focus tutoring it. Your tutor will give more specific help after looking at your efforts towards getting correct result and point where you have got stuck.
